hello,
i was on stock 4.1 and was unlocked with freegee. i then tried to relock it which kinda faild. i was able to flash the kitkat kdz though and everything IS ok.
after that i again used freegee and unlocked it!
so now i want to flash cm11 (and cm12 in the future) and custom kernels. but i dont want anything to happen to my device.
what should i do to relock my device and then use this method?
thank you very much and have a happy new year!
hey yogivin I appreciate it but since Im alittle scared Im gonna ask some Questions?
see I have first Restored EFS backups & then relocked! Yeah google logo has been gone! All happend in a day on stock 4.4.2!!!
but this time I get the secure booting error on the first LG logo not the second!
guys dont be madness if im not trying to flash quickly! Im just alittle scared of flashing with download mode!I 've heard there's possibility perm break my device!? So thats why I'm scared!
so what should I use to flash? read many threads, Just want to ask your opinions!
Q: LG flashtool or LGNPST or KDZ updator?which is safer?how much battery is needed at least?
One repairer said I can flash your OG with box!but I guess that means opening the phone! I hate opening my OG!!!
you know flashing couldnt fix the freegee problem right?
Q: SO Is that possible that I flash & after that I get Secure booting on first lg logo again?
IF NOT, I'll do that!
hey dears Im seriously waiting for your help... I realy appreciate it!
well i guess u have to keep t backup of EFS and other backups..so that u can relock it whneva u want..
Hi guys
problem is when I tried to connect the charger while phone was off,didnt charge!
just phone started to boot!
so I restored the EFS backups & then Relocked bootloader!ALL on the stock 4.4.2a.
so there shouldnt be any problem! but after restart I got Secure booting error on the first lg logo!why that happend? I cant even charge phone again !but I have download mode.
will flashing kdz fix that error???
I've Read that flashing kdz doesnt work while unlocked! here:
http://xdaforums.com/show....php?t=2667398
but as I know IM locked! only secure booting error!
I wanna back to stock & never unlock again... I love lg stock!
Q: I just want to make sure, will lg flash tool or kdz updater or etc surely fix secure booting error?
I only wanted to experience cwm & custom roms! I got a Nandroid & copied in pc by the way!
plz help me Im confused...
Hey body your last situation has given me some hope!
Im gonna flash tomorrow & see if the security problem can be solved!
just stay a while! plus I said I restored EFS & relocked!
if you want to relock with freegee, try this:
FIRST CHARGE YOUR phone 100%! you cant when you get security problem...
then relock & after relock, restore efs backups - copy the backups in pc first
you know I guess you will get the security problem again!
but at least you have fully charged phone!!
not 50% like me.... :crying:
Im gonna give my OG e975 to some repairer to flash! my pc is terrible!
so I'll give you guys the result...
hope flashing will fix...
also I got the 4.4.2 KDZ (970) MB by giving the S/N to some lg site! that was so easy!!downloaded with ADM! :crying:
no one told me, is 50% charge enough for flashing or not???

Just the place I got my 4.4.2 E975a stock rom.
just give the S/N & get your last kdz
hey guys!
I have some good advice for you
I unlocked & relocked with freegee & faced secure booting error.
so today I gave my phone for flashing to an experienced guy.
yeah! every things gooood! problem of security solved!charging while off solved!
& The good advice:
Don't take any risk by flashing them with that useless tools!(in freegee problem at least)
believe me 5$ is not that much worthy even against the "possibility" of breaking!
Im proud to be coward for flashing in booting problem!
your only hope is download mode! what if you lose it?
You need to hold volume down & connect usb for download mode?
So try flashing with box! yeah! that guy connected the box to pc & phone to the box!
Just the time he connected the usb to device, it went to download mode automatically with no button!
it seems even the phone likes the box usb more than pc usb!
also no need to open the device! Thats for unbreaking I guess.
in 10 minutes & 0%(maybe) possibility of beaking, the phone flashed & started up!
no S/N changing! because I restored the EFS I think(not sure).
no flash tool softs! He is flashing all sami,sony,lg,htc etc with an special app named octopus .box was Dlink.
believe me there are better options than that kdz updater etc...
Anyway try whatever you want! I just described what I did, as I promised!
now I've got the little OTA updates of 4.1.2 & gonna root it & install xposed & enjoy it!
dont want to get 4.4.2! I wanna enjoy Eco Mode! & Dalvik with xposed!
maybe unlocking with first method later...

after that will able to flash the stock KDZ without any problemMethod 1: Unlock the bootloader
http://www.mediafire.com/download/kzbp2gicuj22cv5/Tool_Root_Unlock_BL_4.1.2_edited.zip
Advantages:
- fastboot functions: Start, Power Off, Recovery mod, Restart Bootloader
- Easy on the function
-Cons:
- To Relock, you have to flashed KDZ
now the device comes in life again
but you find the device is not properly working may be sim or gprs or wifi or something else.
now have to unlock bootloader again by adb with this method

Can you also add the step by step procedure to unlock bootloader using the first method? As in wether your phone should be in download mode, charge only mode etc etc.
Hey
Yesterday I flash CM11 over stock 4.1.2 on my Optimus G (E975) and later decided to go back to stock again.
Everything was done witouht problems using nand back up with CWM
But later I realiced that M5 was out and, once again tried to install it but I couldnt
Dont know what happen but now while device is turning on, or trying to go into recovery or dowload mode screen is BLACk.
Device is working properly, I mean I turn it off/on and no problem. Just cant enter fastboot, recovery or download mode.
I tried a couple method to go back to stock using KDZ but proceess stop and nothing, just keep pressing power buttom and phone reboot (just black screen during the process)
Please, any ideas/suggestions
O no please.
I follow method one, I get succes message and now my wifi refuses to turn on. WTF
Update 2:
Now Im screwed. I tried to install another recover with Rom Manager and now phone refuses to turn on.
Something is detected in the pc while conecting it but I have only a black screen
Please what can I do??
Yes but I could solve that problem now.
One thing I learned: I will never install a custom rom on my OG. I had several devices before this one and always with custom roms. But with LG there are so many risks and problems to perform needed actions
Thanks
